Wenn 你构建你的应用程序,从你的 ui 文件qmake
生成。h
所以例如自动ui_dlg_about.ui
翻译成a ui_dlg_about.h
。通常在名为 GeneratedFiles 或类似的文件夹中。然后,您可以通过创建以下内容来创建一个可在应用程序中使用的可自定义对话框类:
dlg_about.h
#include "ui_dlg_about.h"
#include <QDialog>
class dlg_about : public QDialog, protected Ui::ui_dlg_about
{
Q_OBJECT
public:
dlg_about(QWidget* = 0);
public slots:
void toggle_dockwidget();
};
dlg_about.cpp
#include "dlg_about.h"
dlg_about::dlg_about(QWidget* parent) : QDialog(parent)
{
setupUi(this);
QObject::connect(this->somebutton, SIGNAL(clicked()), this, SLOT(toggle_dockwidget()));
}
void dlg_about::toggle_dockwidget()
{
if(something){
this->dockwidget->setVisible(true);
}else{
this->dockwidget->setVisible(false);
}
}
您的对话框也有可能不是从其派生而来,ui_dlg_about
而是将其作为成员:
dlg_about.h
#include "ui_dlg_about.h"
#include <QDialog>
class dlg_about : public QDialog
{
Q_OBJECT
public:
dlg_about(QWidget* = 0);
public slots:
void toggle_dockwidget();
protected:
Ui::ui_dlg_about ui;
};
dlg_about.cpp
#include "dlg_about.h"
dlg_about::dlg_about(QWidget* parent) : QDialog(parent)
{
setupUi(this->ui);
QObject::connect(this->ui.somebutton, SIGNAL(clicked()), this, SLOT(toggle_dockwidget()));
}
....
